Description

  The present invention relates to a packaging material set.

  Fruits and vegetables (vegetables and fruits) are to be transported by being accommodated in a tray (a box having a low top with an open top) formed from corrugated cardboard sheets, as described in, for example, Japanese Patent Application Laid-Open No. 2012-101829. There are many. Generally, as a fruit and vegetable tray, it is formed from one cardboard sheet, and has a rectangular bottom plate panel, four side wall panels connected to the four sides of the bottom plate panel, and the side wall panels. What assembled the sheet | seat for trays which has a connection panel for hold | maintaining between side wall panels in a square cylinder shape is used.

  In addition, fruits and the like having a nearly spherical shape are generally accommodated in the tray by taking various protective measures so that they do not collide and damage each other inside the tray. Examples of such means for protecting fruits and the like include, for example, a holding member (for example, see Japanese Patent Application Laid-Open No. 2003-261181), which is formed from a resin molded body, a pulp product, or the like and has a recess into which each fruit or the like is fitted. A plurality of sales containers (for example, refer to Japanese Patent Application Laid-Open No. 2005-306448) and the like that store a certain amount of fruits or the like serving as a sales unit are well known.

  For example, when accommodating relatively fragile fruits and vegetables such as strawberries, figs, mangoes, tomatoes, etc., the use of protective means such as the above-mentioned holding members and sales containers cannot sufficiently prevent the damage. There is. In particular, since the pressure is easily applied to the bottom of the fruits and vegetables by vibration or the like, it is desired to improve the buffering effect of the bottom of the tray.

  In view of the above inconveniences, an object of the present invention is to provide a packaging material set that can form a packaging body that can prevent the stored article from being damaged.

  A packaging material set according to one aspect of the present invention made to solve the above-described problem is formed from a sheet of corrugated sheets formed from a single cardboard sheet and assembled into a tray having an open top, and a single cardboard sheet. And a cushioning material set that is at least partially inserted into the inside of the tray, wherein the tray sheets are alternately arranged in the left-right direction to form a rectangular tubular body in an assembled state. A pair of first side panels and a pair of second side panels, and extending from the lower edges of the pair of first side panels and the pair of second side panels, and sealing the lower end of the rectangular cylindrical body in an assembled state. A pair of first bottom flaps and a pair of second bottom flaps that form a bottom body that extends from the upper edges of the pair of first side panels and the pair of second side panels; A pair of first inner surface panels and a pair of second inner surface panels that are folded inside the pair of first side panels and the pair of second side panels, and the buffer sheet is disposed inside the bottom body of the tray. A pair of rectangular insole panels to be stacked; a pair of connection panels extending from a pair of opposing side edges of the insole panel; and stacked further on the inner side of the first inner surface panel of the tray; It has a pair of lid flaps that extend from the leading edges and form a lid that seals the upper opening of the rectangular cylindrical body by abutting the leading edges.

  The packaging material set is configured to further overlap the bottom panel of the buffer sheet on the bottom of the tray formed by the two pairs of bottom flaps, thereby sufficiently reducing the impact applied to the bottom of the contained article. Can do. In addition, the packaging material set has a structure in which all the peripheral walls of the tray are formed by overlapping the corrugated cardboard sheets, and by providing a pair of lid flaps on the cushion sheet, the impact from the side can be sufficiently reduced. it can. Therefore, the packaging material set can more reliably prevent the stored article from being damaged.

  In the packaging material set, it is preferable that the length in the left-right direction of the pair of lid flaps is larger than the length in the left-right direction of the first side panel. Thus, when the length in the left-right direction of the pair of lid flaps is larger than the length in the left-right direction of the first side panel, the lid flap falls to the inside of the tray and damages the article accommodated by the leading edge. Can be prevented.

  In the packaging material set, the tray sheet is formed by extending at the base end portion of the second inner surface panel so as to bite into the second side panel, and protrudes upward from the rectangular cylindrical body in an assembled state. It may further include two pairs of protrusions, and the buffer sheet may include two pairs of slits that are formed on the lid flap and receive the protrusions. Thus, the tray sheet further includes the two pairs of protrusions, and the buffer sheet has the two pairs of slits for receiving the protrusions, whereby the lid flap can be kept closed. Therefore, protection of the accommodated article is further ensured.

  In the packaging material set, a pair of openings corresponding to the protrusions are formed in an assembled state at a base end portion of the second bottom flap, and a pair of openings corresponding to the protrusions in an assembled state at a distal end portion of the second inner surface panel. A notch may be formed. Thus, a pair of openings corresponding to the protrusions are formed in the assembled state at the base end portion of the second bottom flap, and a pair of notches corresponding to the protrusions in the assembled state at the distal end portion of the second inner surface panel. When the packaging body using the packaging material set is stacked up and down, the protrusions of the lower packaging body are fitted into the openings and the notches of the upper packaging body, and the load collapses. Can be prevented.

  In the packaging material set, it is preferable that the length of the leading edge of the connection panel is larger than the length of the base edge. Thus, when the length of the leading edge of the connection panel is larger than the length of the base edge, the middle bottom panel and the connection panel of the buffer sheet can be inserted into the tray formed by assembling the tray sheet. It becomes easy.

  As described above, the packaging material set according to the present invention can form a package that can prevent the housed article from being damaged.

It is a typical top view (development drawing) which shows the composition of the packaging material set of one embodiment of the present invention. It is typical sectional drawing of the box formed by assembling the packaging material set of FIG. It is a typical perspective view which shows the package using the packaging material set of FIG. It is a typical perspective view which shows the mode of unpacking of the package of FIG.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.

[Packaging material set]
FIG. 1 shows a packaging material set according to an embodiment of the present invention. In addition, in FIG. 1, a thick solid line shows the cutting line which cut | disconnected the sheet material, and a thin continuous line pushes and pushes on the back surface (surface arrange | positioned inside the package using the said packaging material set). Indicates the ruled line.

  The packaging material set is assembled in a box shape as shown in FIGS. 2 and 3 and is used to form a packaging body containing one or a plurality of articles P.

  Examples of the article P packaged by the packaging material set include fruits and vegetables such as strawberry, fig, mango, tomato and the like that are relatively easily damaged and leafy vegetables. Such an article P may be accommodated in a state of being held by a holding member S having a plurality of recesses like an egg pack.

  The packaging material set is formed from a single cardboard sheet, and as shown in FIG. 4, is formed from a tray sheet 1 assembled in a tray T opened at the top and a single cardboard sheet, and at least partially. And a buffer sheet 2 inserted inside the tray T.

  The corrugated cardboard sheets forming the tray sheet 1 and the cushioning sheet 2 of the packaging material set are not only those in which both sides of one core are sandwiched between a pair of liners, but also each core between three liners. May be a so-called double flute in which is inserted, or a so-called single-sided cardboard in which a liner is attached only to one side of the core. In the packaging material set, the type of cardboard sheet forming the tray sheet 1 may be different from the type of cardboard sheet forming the buffer sheet 2.

<Tray sheet>
The tray sheet 1 includes a pair of first side panels 3 and 4 and a pair of second side panels 5 and 6 that are alternately arranged in the left-right direction, and the side panels 3 to 6 are assembled in a square tube shape. A joint 7 connected to one end of the first side panel 3 located at one end in the left-right direction and bonded to the inner surface of the other end of the second side panel 6 located at the other end so as to form a body. . The joining of the joint 7 to the second side panel 6 can be performed using, for example, an adhesive, a stapler, or the like.

  The cardboard sheet forming the tray sheet 1 is preferably oriented so that the ridgeline of the core extends in the vertical direction in order to improve the strength of the rectangular cylindrical body formed from the side panels 3-6.

  In the present embodiment, the length in the left-right direction of the first side panels 3, 4 is larger than the length in the left-right direction of the second side panels 5, 6. That is, in the tray sheet 1, the first side panels 3 and 4 define long sides in the rectangular planar shape of the tray T, and the second side panels 5 and 6 define short sides.

  The tray sheet 1 extends from the lower edges of the pair of first side panels 3 and 4 and the lower edges of the pair of second side panels 5 and 6 and seals the lower end of the rectangular cylindrical body in the assembled state. A pair of first bottom flaps 8 and 9 and a pair of second bottom flaps 10 and 11 forming a bottom body, an upper edge of a pair of first side panels 3 and 4 and a pair of second side panels 5 and 6 A pair of first inner surface panels 12, 13 and a pair of second inner surface panels 14 that extend from the edges and are folded inside the pair of first side panels 3, 4 and the pair of second side panels 5, 6 in an assembled state. , 15.

  The tray sheet 1 forms a flat rectangular tubular body having a small vertical length by the side panels 3 to 6, and the second bottom flaps 10 and 11 are bent inside the lower end opening of the rectangular tubular body, Further, the bottom of the tray T is formed by folding the first bottom flaps 8 and 9 and butting the leading edges of the first bottom flaps 8 and 9 together. For example, the tray T is attached with adhesive tape along the joint of the leading edges of the first bottom flaps 8 and 9, or the first bottom flaps 8 and 9 and the second bottom flaps 10 and 11 are bonded with an adhesive. The assembled state of the bottom body can be maintained by pasting together. Note that “matching” is not limited to the state of contact, and may be a state of forming a small gap.

  Furthermore, the sheet | seat 1 for trays overlaps the inner surface panels 12-15 on the inner surface side of the side panels 3-6 by folding the inner surface panels 12-15 180 degrees with respect to the side panels 3-6. Thereby, tray T which assembles sheet 1 for trays becomes a double structure in which a peripheral wall has side panels 3-6 and inner surface panels 12-15.

  The tray sheet 1 is folded from the unfolded state shown in FIG. 1 with the first side panel 3 positioned at one end in the left-right direction on the inner surface side of the adjacent second side panel 5 and the second side surface positioned at the other end in the left-right direction. It is contemplated that the panel 6 is provided to the user in a state where the panel 6 is folded on the inner surface side of the adjacent first side panel 4 and the joint 7 is adhered to the second side panel 6.

  Two tray sheets 1 are formed at the boundary between the first side panel 3 and the first inner surface panel 12 and at the boundary between the first side panel 4 and the first inner surface panel 13 respectively, and are long in the left-right direction and have corners. It has a rectangular upper opening 16 that is rounded and chamfered. The upper opening 16 discharges moisture released from the article P to the outside in a box formed by assembling the packaging material set, or cools the article by introducing external cold air into the box. Acts as a vent that allows that.

  Each upper opening 16 is formed vertically symmetrically about a ruled line that demarcates the boundary between the first side panels 3, 4 and the first inner panel 12, 13, and in the tray T formed by assembling the tray sheet 1, The upper edge overlaps the edge below the ruled line, and a notch is formed at the upper end of the side wall.

  In addition, the tray sheet 1 is formed two each at the boundary between the second side panel 5 and the second bottom flap 8 and at the boundary between the second side panel 6 and the second bottom flap 9, and is long in the left-right direction. It has a rectangular lower opening 17 with rounded corners and chamfers. Similarly to the upper opening 16, the lower opening 17 also functions as a vent hole in a box formed by assembling the packaging material set.

  In order for the lower opening 17 to function as a vent hole, the tray sheet 1 is formed on the side circles of the first bottom flaps 8 and 9 so as to overlap the second bottom flaps 10 and 11 side portion of the lower opening 17 in the assembled state. Two pairs of bottom cutouts 18 and two pairs of inner cutouts 19 formed at the leading edges of the second inner surface panels 14 and 15 so as to overlap the second side panel 5 and 6 side portion of the lower opening 17 in the assembled state. And further. The bottom cutout 18 and the inner cutout 19 can be formed larger than the lower opening 17. In particular, it is preferable that the length of the inner notch 19 in the vertical direction is sufficiently large.

  The tray sheet 1 is formed by extending at the base end portions of the second inner side panels 14 and 15 so as to bite into the second side panels 5 and 6 and projecting upward from the rectangular cylindrical body in the assembled state. 20 Thereby, the outer side notches 21 having a shape complementary to the protrusions 20 are formed in the second side panels 5 and 6. In other words, the upper side of the second side panels 5 and 6 is provided with a convex cutting line with the ruled line defining the boundary with the second inner side panels 14 and 15 as both ends. 6, an outer notch 21 is formed, and a projection 20 is formed at the base end of the second inner panel 14, 15.

  These protrusions 20 pass through the bottom cutout 18 and the lower opening 17 of the upper packaging body and are accommodated in the inner cutout 19 when a plurality of packaging bodies using the packaging material set are stacked one above the other. Thereby, a plurality of packaging bodies using the packaging material set can be engaged with each other to prevent the collapse of the cargo. For this reason, the bottom notch 18, the lower opening 17, and the inner notch 19 are formed at positions corresponding to the protrusions 20 in the assembled state (the same position in the left-right direction).

  Thus, in order to prevent the collapse of the load by inserting the protrusion 20 into the inner cutout 19, the length of the lower opening 17 in the vertical direction within the second side panels 5, 6 (second side panel 5, 5). 6 and the bottom bottom flap 10, 11 from the ruled line above the ruled line) is smaller than the projection length of the projection 20 in the vertical direction, and the vertical length of the inner notch 19 is It is desirable to make it larger than the protruding length in the vertical direction.

<Buffer sheet>
The buffer sheet 2 extends from a rectangular middle bottom panel 22 that is stacked inside the bottom of the tray T formed by assembling the tray sheet 1 and a pair of opposing side edges (long sides) of the middle bottom panel 22. A pair of connection panels 23, 24 that are stacked further on the inside of the first inner surface panels 12, 13 of the tray T, and the front edges of the connection panels 23, 24. It has a pair of lid flaps 25 and 26 that form a lid that seals the upper opening of the cylindrical body.

  The corrugated cardboard sheet forming the cushioning sheet 2 has a ridge line of the core, which improves the strength of the package and secures the strength when the article P is taken out from the tray T together with the cushioning sheet 2. The connection panels 23 and 24 and the pair of lid flaps 25 and 26 are preferably oriented so as to extend in a direction in which the connection panels 23 and 24 are connected to each other.

  In order to insert the inner bottom panel 22 into the inside of the tray T, the length of the long side adjacent to the first side panels 3 and 4 is slightly smaller than the length in the left-right direction of the first side panels 3 and 4. The length of the short side adjacent to the second side panels 5 and 6 is slightly smaller than the length of the second side panels 5 and 6 in the left-right direction.

  Further, the midsole panel 22 may be curved or bent so that the short side is slightly concave inward. As described above, the side edge on the short side of the midsole panel 22 is concave, so that the side edge of the midsole panel 22 is prevented from being caught by the leading edges of the second inner surface panels 14 and 15, and the cushioning sheet 2. Can be easily removed from the tray T, that is, the package can be disassembled.

  The length of the base end edge (boundary line with the midsole panel 22) of the connection panels 23 and 24 is the left and right direction of the first side panels 3 and 4 so that the midsole panel 22 can be easily inserted inside the tray T. It is preferable that the length is slightly smaller than the length. The difference between the length of the base edge of the connection panels 23 and 24 and the length of the first side panels 3 and 4 in the left-right direction is not less than 2 times and not more than 4 times the average thickness of the corrugated cardboard sheet forming the tray sheet 1. It is preferable that

  Further, the lengths of the leading edges (boundary lines with the lid flaps 25 and 26) of the connection panels 23 and 24 are set so that the bottom panel 22 can be easily inserted into the tray T. Preferably, it is slightly larger than the length of the boundary line with the bottom panel 22. Furthermore, the buffer sheet 2 can be prevented from moving in the tray T by bringing the lengths of the leading edges of the connection panels 23, 24 closer to the length in the left-right direction of the first side panels 3, 4. Protection of the accommodated article P can be further ensured.

  It is preferable that the left and right lengths of the lid flaps 25 and 26 are larger than the left and right lengths of the first side panels 3 and 4. Since the length in the left-right direction of the lid flaps 25, 26 is larger than the length in the left-right direction of the first side panels 3, 4, both ends in the left-right direction of the lid flaps 25, 26 are the second side panels 5 of the tray T. 6, the top edge of the lid flaps 25, 26 is prevented from falling into the tray T and damaging the article P.

  The extension length in the vertical direction of the lid flaps 25 and 26 may be smaller than ½ of the length in the horizontal direction of the second side panels 5 and 6. The length of the cover flaps 25, 26 in the vertical direction is smaller than ½ of the length of the second side panels 5, 6 in the left-right direction. A gap functioning as a vent can be formed in the center of the body.

  Each of the lid flaps 25 and 26 is preferably formed with two slits 28 for receiving the projections 20 of the tray T, respectively. Thus, the state which sealed the box body which closed the lid flaps 25 and 26 and assembled the said packaging material set by engaging the protrusion 20 of the tray T with the slit 28 provided in the lid flaps 25 and 26 is carried out. Therefore, the protection of the article P to be accommodated becomes more reliable.

  In order to be able to hold the closed state of the lid flaps 25 and 26 more reliably, the slit 28 is formed in a tapered shape in which the width of the region in the vicinity of both ends decreases toward the end, and the width of both ends is It is more preferable that the thickness is smaller than the average thickness of the corrugated cardboard sheet forming the tray sheet 1. Thereby, the slit 28 can compress the protrusion 20 in the thickness direction to generate a frictional force, and can hold the sealed state of the package more reliably.

  Further, in order to hold the closed state of the lid flaps 25 and 26 more reliably, the direction in which the side edge of the protrusion 20 on the center side in the left and right direction of the second inner surface panels 14 and 15 is inclined to the center in the left and right direction, When the protrusion 20 is engaged with and detached from the slit 28, the tip side portion of the side edge on the center side of the protrusion 20 may be rubbed against the end of the slit 28 to generate resistance. The inclination angle of the side edge can be 3 ° or more and 8 ° or less.

  When the slit 28 has a tapered shape, it is preferable to form the side edge of the lid flaps 25 and 26 of the slit 28 on the center side in the left-right direction in a straight line and bend the outer side edge. Thereby, the protrusion 20 is pressed toward the side of the box, and the second inner surface panels 14 and 15 can be prevented from being lifted from the second side panels 5 and 6.

  The buffer sheet 2 includes two lid openings 29 that are formed at the boundaries between the connection panels 23 and 24 and the lid flaps 25 and 26, respectively, and are long in the left-right direction and rounded at the corners. The lid opening 29 overlaps with the notch formed by the upper opening 16 of the tray T in the package body in which the article P is packaged using the packaging material set, and functions as a vent hole.

  The lid opening 29 also functions as a hand hole for gripping the buffer sheet 2 to take out the buffer sheet 2 from the tray T when unpacking the package using the packaging material set. Therefore, the length of the lid opening 29 in the vertical direction (the direction in which the insole panel 22, the pair of connection panels 23 and 24, and the pair of lid flaps 25 and 26 are connected) is such that a hand can be inserted. Is preferably 2 cm or more and 5 cm or less, and the length in the left-right direction of the lid opening 29 (the direction along the boundary between the connection panels 23 and 24 and the lid flaps 25 and 26) is preferably 5 cm or more and 10 cm or less.

<Advantages>
When the packaging material set is assembled in a box shape and wraps the article P, the bottom panel of the tray T formed by the two pairs of bottom flaps 8 to 11 of the tray sheet 1 is further added to the mid-bottom panel 22 of the buffer sheet 2. Since the plurality of cardboard sheets are stacked on the bottom of the package, the impact applied to the bottom of the article P to be accommodated can be sufficiently reduced.

  Moreover, in the said packaging material set, the surrounding wall of the tray T which the sheet | seat 1 for trays forms is a double structure where all the side panels 3-6 and the inner surface panels 12-15 were piled up, and it buffers further about the long side side. Since the connection panels 23 and 24 of the sheet 2 are overlapped, the impact applied to the article P can be sufficiently reduced even with an external force from the side.

  In the package body in which the article P is packaged using the packaging material set, the lid flaps 25 and 26 are flipped up, and the cushion sheet 2 is placed on the midsole panel 22 as shown in FIG. The article P can be taken out easily and quickly by pulling upward together with the article P from the tray T.
